To all whom it may 0071170272.

Be it known that I, JOSEPH BARRA-TA- FHAUENFELDT'IR, a citizen of the United- States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Submarine Torpedo-Boats, of

which the following is a specification.

Heretofore, the use of steam engines in submarine torpedo boats for supplying the short notice which is the essential requirement of all submarine torpedo boats.

The object of the invention is to provide a boiler room. in submarine tor edo boats which. may be completely out o from the living and working quarters of the boat, whereby the heat emitted from-the boilers and from the boiler room may be prevented from being distributed throughout the said living and working quarters when the boat is submerged, thus making it practical 'to use steam engines for operating the boat on the surface instead of the present oil enpower and consequently higher surface speeds may be obrained than has heretofore been possible in this class of vessels.

The invention consists in dividing the main hull by suitably spaced transverse partitions or bulk-heads, providing a water compartment within the main hull of the boat, and in arranging a closed chamber within the said compartment providing a boiler room, said chamber being of smaller dimensions than the water compartment whereby a water-jacket space is provided around the said chamber which is adapted to be filled with water from the water of flotation,said chamber communicatin with the opposite ends of the boat throng passagewavs which are designed to be closed at each end, whereby to provide air-locksto prevent Specification of Letters Patent.

Patented Apr. e, 1915 the heat of the boiler room from escaping into the boat when the latter is submerged, means being provided for ventilating the boiler room, and for supplying forced draft to the boilers, and means also provided for causing a circulation of water through the waterjacket. These and other features germane thereto constitute the invention, as will be hereinafter fully described and then pointed out in the claims.

In the accompanying drawings, illustrating the invention, Figure 1 is a diagrammatic side elevation of a submarine torpedo boat illustnting the construction and preferred location of my invention, the boilers and their connections being omitted for the purpose of clearly illustrating the construction of the boiler-room. Fig. is a diagrammatic vertical longitudinal section drawn through the boiler room and the adjacent section of the hull of theboat. Fig. 3 is a horizontal section drawn on the line a-a of Fig. 2. Fig. 4: is a vertical transverse section drawn on the line D b 01'' Fig. 2 looking in the direction ind cated by hull airand water-tight to provide a water holding compartment 4. lVithin the compartment l is a closed, preferably cylindrical chamber 5, of less diameter and length than the said compartment, and which is construc d of shell plating 6 and a series of eX- ternal ribs or it'r'ames 7.. the whole being of sufficient strength to withstand the pressure incident to submergence. The chamber 5 is held in position within the compartment 4' by suitable frames 8 (Fig. 4) preferablyrive-ted to the ribs 1' of the main hull and to the ribs or frames 7 of said chamber. The space thus formed between the hull ofthe boat and the chamber 5 provides a water-jacket.

trolled by a valve 9 the stem 10 of-which ex-' tends upwardly into the boiler room and is provided with a hand wheel 10 as shown. The ends 5 of the chamber are provided .with openings 11 which are located opposite opening 12 formed in the adjacent transverse partitions or bulk-heads 2 and 3, and within each pair of adjacent openings is fitted a frame 13 providing passages or doorways leading into the boiler-room. The frames are connected airand water-tight to the ends 5 of the chamber 5 and to their respective adjacent bulk-heads 2 and 3, the

ends of each frame being extended through their openings 11 and 12 and provide seats for doors 14; which are hinged adjacent to one'side of the frames in suitable manner and control the assages through the said frames. When he doors are closed and locked the passages form air-locks to prevent the escape of the heat from the boiler room into the living and working quarters of the boat as will be hereinafter further described. Any suitable means commonly used for locking doors and hatches in submarine boats may be employed for locking the doors 14 in closed position.

Within the chamber 5 is arranged a horizontal partition 0r floor 15 the space above which provides aboiler-room 16 in which is located preferably four steam boilers or generators 17 Which may be of coal or oil burning types and of any suitable design. The smoke-stacks 17 of the boilers open through the top of the chamber 5 into an exhaust manifold 18' built upon and connected air- I and water-tight to the top of the said chamber and extending through an opening formed in the plating of the hull 1, said manifold being also connected to the plating of the hull 1 airand water-tight by means of suitable'angle frames. The top of the manifold terminates in a short pipe section 18 and is provided with a cover 19 designed to be closed and looked upon the top of said pipe section airand water-tight when the boat is submerged. As shown in dotted lines in Fig. 2 the pipe section 18 may be fitted with an extension 20 which may be either a single removable pipe or smoke-stack or a telescopic smokestack designed to be withdrawn into the manifold 18 when the cover 19 is to be closed. The smoke-stacks 17 extend slightly above the plating of the chamber 5 and are provided with annular flanges which are riveted to the plating of said chamber, and their upper ends are provided with COVQFS 21. which are designed to be locked upon the tops of the said smoke-stacks airand watertight to prevent ingress of water to the boiler tubes in the event of water leaking into the manifold. Any suitable means (not shown) may be employed for opening and closing the covers 21 from within the boiler room. The manifold is constructed with a double wall, the space between the walls providing an air-jacket, and the said smokestacks 17 are surrounded by sleeves 17 i'iroviding air-jackets which open into the manifold 18, the purpose of the jackets being to prevent the heat radiating from said stacks from entering the boiler room. Water is supplied to the boilers through pipes 22 extending from fresh water-tanks (not shown) built in the boat, steam is conducted from the boilers suitable engines (not shown) through pipes i As shown in Fig. i, the smoke-stacks 17' of the boilers open into the manifold which is arranged exteriorly of the chamber while in Fig. 5 the manifold 81 is connected direct to the smoke chambers of the boilers and is arranged entirely within the chamber 5 and from the manifold 81 extends a single smoke-stack 82 which is extended up through an opening in the top of the chamher 5 and through an opening in the plating of the hull 1 in suitable manner. It will, of course, be understood that the smoke-stack 82 will be provided with a cover similar to the pipe section 18 of the manifold 18.

With the use of coal burning boilers, air is forced into the ash-pits of the boilers through pipes 25 provided with branches 25' which open through the bottom of the ash-pits. The pipes 25 extend from suitable blowers 26 mounted within boiler room and connected to one end of the shafts of suitable motors 27, the inlets to said blowers being connected by pipes 28 which extend through openings formed in the plating of the chamber 5 and through openings in the plating of the hull 1 and have their upper ends designed toreceive removable hoods 28. To ventilate the boiler rooinl provide suction 'blowers 99 which are connected through clutches 30 with theopposite ends of the shafts ofthe motors 27 and to the outlets of said suction blowers are connected pipes 31 which also extend through the plating of the chamber 5 and the plating of the hull 1 and are provided with removable ex haust pipes 32 which, like the inlet pipes 28 are extended upwardly a suitable distance above the main hull or deck of the boat. Valves-(not shown) control the passage through the pipes 28 and 31 and are operated by hand wheels 33 Figs. 2 and it. The admission of air to the ash-pits of the boilers is controlled by valves 34 arranged in the pipes 25 to fold or seat over the inlets to the branches 25. \Vith the use of oil burners where forced draft into the ash-pits of the boilers is unnecessary, the valves 31- are closed so that the air passing through the pipes 25 will be permitted to escape 1 through the ends of said pipes into compartments (hereinafter described) formed below the horizontal partition 15 of the boiler roonn the air being permitted to. es-

cape from the compartments into the boiler the chamber room through slots 15 formed in the said horizontal partition 15 in front of .the boilers 1,7. With the use of oil burners the necessary draft and the hot air in the boiler room will be drawn into the fire-boxes through the doors opening into the same and carried off, with the fumes from the burning oil, through the smoke-stacks 17. Also with the use of oil burners, it may be stated, the clutches 30 are adjusted to throw the suction blowers 29 out of operation so that the hot air in the boiler room will be carried ofl through the fire-boxes of the boilers. I

The horizontal partition is centrally supported by parallel longitudinal girders (Fig. 4), having their longitudinal edges connected airand water-tight to the partition 15 and to the plating 6 of the chamber 5, respectively, and-their ends connected airand water-tight to the ends of the chamber 5. In the compartments thus formed between the girders 35 and "the sides of. the chamber 5, are series of. transversely arranged supporting frames 36 for the partition'15, and located between the said girders is an inverted U-shape trough 37 (Fig. 4:), having its lower longitudinal edges connected airand Water-tight to the plating of 5, and its ends extended through the ends 5 of the chamber and connected air-- and water-tight to the transverse *partitions 2 and 3 and surrounding openings therein. The longitudinal edges of the. trough 37, between the ends of the saidchamber and the transverse partitions 2 and 3 are closed by suitable plates, and it will be understood that the said plates, as well as the sides and the top of the trough 37 are connected airand water-tight to the ends ofthe chamber to prevent'water enter ing said chamber when admitted to the water-jacket. The space thus formed by the trough provides a passage-way between the forward and after ends of the boat when i the' doors controlling the passages into the boiler room are closed. The space around the trough 37 provides a water-jacket intowhich water is admitted from the compartment 4 through openings 38 (Fig. 4), formed in the plating 6 of the chamber Suitable valve controlled vents (not shown) will, of course be provided for venting the compartment 4-, and the water-jacket around the trough 37.

When the boat is operating on the surface, water is admitted to the compartment 4- around the chamber 5, to the Water of flotation, and when t e boat is submerged the said compartment is completely filled so that it not not only provides a water-jacket entirely around the chamber 5, but also .then serves as a. ballast-tank. In order to create a circulation of water Within the compartment or Water-jacket I arrange a pipe 39 the surrounding body of water. The pumps 40 are operated by motors 42. The pipes 39 are open at their free ends and are provided with inlets throughout their length so as to withdraw the water from the compartment throughout its entire length. When the Water circulating pumps are in motion, it will be understood that the sea-valve 9 is also open so that-water is permitted to enter the compartment as it is withdrawn therefrom and pumped overboard, thus maintaining a constant circulation of water through the Water-jacket which consequently keeps down the temperature in the boiler-room in the same manner as with. all explosive engines.

In Fig. 5, I illustrate a slightly different method of causing a circulation of water through the water-jacket or compartment around the chamber In this construction the plating of the hull 1 is provided with openings 50 leading into the water-jacket or compartment which are surrounded by hoods 51 having gate valves 52 controlling the inlets to and the outlets through said hoods.- The valves 52 are located within the hoods and the latter are also provided with out-' wardly opening gate valves 54 which-are 100 hinged to the outer faces of the hoods, the said valves 54 of the forward hoods being hinged to the rear ends thereof to thus serve, when open and the boat is under way, to direct water into the hoods and into the 105 water-jacket, while the valves 54 of the hoods at the after end of said water-jacket are hinged to the forward ends of their hoods and thus serve, when open, as shields to permit the water'to freely escape from said no water-jacket.

When operating on thesurface' of the water under steam power the air pumps or fans are set in motion as previously described, and as the doors of the boiler room and the hatches leading into the main hull of the boat are open it will be apparent that the boiler room as well' as the working and living quarters of the boat are kept cool and supplied with fresh air so that no serious merged operations to be carried out without the diiliculties and inconveniences heretofore experienced with the use of steam power in submarine vessels.

lVhile l have shown my invention as installed in a single hull submarine boat I do not wish to be understood'as limiting myself to this design of boats, as it will be appreciated that the invention may beearried out in boats of double hull construction. In this application of my invention the transverse partitions or bulk-heads 2 and 3 would,

of course, be connected to the inner hull of the boat and suitable openings provided in the inner hull to aflord communication bei as tween the water space betweenthe hull sections and the water-jacket spaces at the ends of the chamber 5. As this construction will be obvious to any one skilled in the art to which the invention relates, I have not thought it necessary to illustrate the same. While not shown it will also be obvious that the usual means employed for expelling the Water from the ballast tanks of this class of boats will also be used to pump all of the water from the compartment 4 should it be desired to do so.
